A memory error is detected during a read
from configuration memory. This also
indicates a hardware failure, but the system
may continue to initialize successfully. The
configuration from another Unit should be
saved to this Unit as soon as possible.

processing. The UltraMatrix waits to receive a
kernel or main firmware file from the bottom

cable supplied with the UltraMatrix as
described in the Serial Port section, start a
terminal emulator and transfer the file using
an ASCII file transfer protocol.
